This is fine, except that if Date.parse fails because it doesn't like the format you're still going to get a parse error, which I suspect may have been what you were trying to do. Try this instead:

```ruby
@publish_date = Date.parse(@document[:publish_date]) rescue Date.today
```
I don't always recommend using an inline `rescue` like that, but I think that in this case it fits.
